Embodiment 1

[0042] Such as Figure 1 ~ Figure 3 and Figure 8 ~ Figure 10 As shown, this embodiment provides a manufacturing method of an LED display screen module, and the manufacturing method includes:

[0043] Such as figure 1 As shown, firstly, step 1) is performed, a PCB substrate or glass substrate 101 is provided, and the Mini LED chip 102 is flip-mounted on the PCB substrate or glass substrate 101.

[0044] The PCB substrate or glass substrate 101 includes a first surface and a second surface, the first surface is formed with electrodes for connecting with the Mini LED chip 102, and the second surface has a connecting portion for connecting with the driving chip . The PCB substrate or glass substrate 101 may be a single-layer or multi-layer board, and there are interconnecting wires inside the PCB substrate or glass substrate 101. The electrodes include a first electrode 103 and a second electrode 104, and the first electrode 103 may be Positive electrode or negative electrode. The se...

Embodiment 2

[0056] Such as Figure 1~2 , Figure 4 and Figure 8 ~ Figure 10 As shown, this embodiment provides a method for manufacturing an LED display screen module, the basic steps of which are the same as those in Embodiment 1. The difference from Embodiment 1 lies in:

[0057] The shape of the dispersively coated laminating material 203 is a line segment array pattern, and the line segment array pattern is a plurality of line segments interlaced in a network.

[0058] In a specific implementation process, the line segment array pattern is a plurality of line segments interlaced in a rectangular mesh, such as Figure 4 As shown, the coating area is divided into several equal sub-areas in the transverse and longitudinal directions, such as m parts in the transverse direction, m≥1, n parts in the longitudinal direction, n≥1, and m and n may be equal or not equal. A glue spreader is used to coat the laminating material 203 in the transverse direction, and the coating path is a straight line ...

Embodiment 3

[0060] Such as Figure 1~2 , Figure 5 and Figure 8 ~ Figure 10 As shown, this embodiment provides a method for manufacturing an LED display screen module, the basic steps of which are the same as those in Embodiment 1. The difference from Embodiment 1 lies in:

[0061] The shape of the dispersion-coated laminating material 203 is a line segment array pattern, and the line segment array pattern is a spirally bent line segment.

[0062] In a specific implementation process, such as Figure 5 As shown, from the center of the coating area as the starting point, the laminating material 203 is spirally coated to the periphery. It is also possible to spirally coat the laminated material 203 from the periphery to the center point of the coating area. In the process of coating the laminating material 203, the amount of glue of the laminating material 203 can be adjusted according to the position of the spiral part. For example, the amount of the laminating material 203 located in the cen...

Abstract

The invention provides a manufacturing method of an LED display screen module. The manufacturing method comprises the steps of (1) inversely mounting a Mini LED chip on a PCB or a glass substrate; 2)providing a release film, coating the release film with a film pressing material, and coating the release film with the film pressing material in a distributed manner; (3) aligning the coating area of the release film with the groove body, pressing the release film into the groove body in a manner that the surface, provided with the Mini LED chip, of the PCB or the glass substrate faces the coating area, enabling the release film to be attached to the groove body in a conformal manner, paving the film pressing material towards the periphery, and coating the Mini LED chip with the film pressing material; and 4) curing the film pressing material to form a film pressing layer. Through the novel coating method of the film pressing material, the film pressing material is dispersed as much as possible before film pressing, the film pressing material is dispersed on a small area during film pressing, and finally, the film pressing layer has relatively high uniformity in thickness and components. The LED display screen module has relatively high ink color consistency.

Description

Technical field [0001] The invention belongs to the field of semiconductor display design and manufacturing, and particularly relates to a manufacturing method of an LED display screen module. Background technique [0002] At present, with the development of LED displays, LED displays are gradually being applied in various fields. With the innovation and development of LED display technology, the small-pitch, seamlessly connected LED display module with high resolution per unit area has become the mainstream product of LED display. It can display higher-definition graphics images and videos, or Display more videos and images, especially in the application of image stitching, which can achieve seamless and arbitrary large-area stitching. [0003] The LED display module is one of the main components of the finished LED display. At present, there are several methods for making small-pitch display modules: 1. Discrete device (SMD); 2.4 in 1 Mini LED (IMD); 3. chip on board (COB). Ne...
